p-Cycles present a very interesting approach to building survivable networks. They have been widely studied for unicast and recently for multicast traffic. For anycast traffic almost no research have been done. We will discuss a new p-cycles version, called Anycast-Protecting p-Cycles, introduced in our previous paper. We provide detailed description of some new properties, ILP models, results and...
Most of previous research on survivable networks has been focused on protecting the unicast traffic against random failures. In this paper we propose a new approach, called RA (resistant-to-attack), to provide protection of anycast and unicast communications against attacks on irregular (e.g. scale-free) networks. We use the single backup path approach to provide protection against a single node failure...
Most of previous research on survivable networks has been related to unicast communications. In this paper we propose a new approach to network survivability of anycast communications. To the best of our knowledge, anycast defined as one-to-one-of-many technique has not received much attention recently. To provide network survivability, we use the single backup path approach, i.e. each demand has...
Intensive and extensive development of computer networks generates the problem of providing a suitably high level of network survivability. A lot of research has been done in this area in recent years, including studies associated with the use of a modern tool called p-cycles. p-Cycles not only provide a high level of protection, but also achieve it at a quite low cost. Until now, p-cycles have been...
This work focuses on the problem of survivable network design with simultaneous unicast and anycast flows. The motivation for this problem is twofold. First, in recent years we can observe an increasing popularity of network services using anycast flows (e.g. content delivery networks (CDN), domain name service (DNS), peer-to-peer (P2P)) systems. Second, current users require reliable network services,...
The paper centers around the problem of survivable network design for simultaneous unicast and anycast flows. This problem arises from the growing popularity of network services using anycast flows (e.g. Domain Name Service (DNS), peer-to-peer (P2P) systems, Content Delivery Networks (CDN)) and the increasing need to provide reliable network services. We formulate four new optimization models of joint...
